See above in blue.Guys a few more questions...
- How to clean the pistons crowns while they're in place, assuming I do not want to pull them up and further mess with stuff more than I have to. How to prevent debris / dirt from falling off depeer into the engine? I wouldn't try it. You'll get debris in all sorts of places you don't want to. Either take the pistons out and clean them, or just leave them. The top of the piston will always have a thin layer of carbon build-up, so as long as it's not something extreme, I'd leave that alone. If it looks about like this, it's fine.
- Does pulling off the cylinder head requires at any stage to pull the shims / buckets out of their place? Considering I am looking to steer off a valve adjusment at this time. No, not if you pull off the whole head as a unit. But if you remove the cams and then put them back in, you should check the valve clearance again.
- Rubber O-rings. In the manual Kawasaki have instructions for "Grease" and "Silicone Grease", While replacing the thermostat housing and later posting about that here, I learned that silicone grease is better for o-rings. However in the manual it states to use "grease". not "silicone grease". The engine have a few that requires replacing once you open it up, together with the exhaust o-rings and CCT o-ring as well. Should you use "normal" grease like kawa states in the manual, or silicone grease? Is it even safe to have grease coating on rubber o-rings that are inside the engine? Use whichever.
- Kawsaki calls for using 2 liquid gaskets throughout this entire process just for the cylinder head cover. In the manual they say to apply the first one and draw a line all over it. Then they call for the second one and say to use it only on the lips of the cover, but they already drawed over it for the first one...? I'm not sure I understand what you mean here. Just apply the liquid gasket on the surfaces they mention, let it sit for a bit and then continue with installation.
- Cam sprockets bolts. Kawa says to use a non permant locking agent. What to buy? I am assuming you need one that stands heat, but what kind. I have loctite 242. Is that good enough? Yeah blue loctite is fine.
- Does rubber o-rings and engine gaskets have a shelf life? Assuming it's being stored well... Yes but I think it's pretty long, like several years or more. Depends on the material too since there are various kinds of "rubber".
